Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 6) - Measurement Examples

Stuart Yaniger continues to examine ways to create a low-cost system for lab-grade audio electronics measurements. In this article, a few measurement examples are used to illustrate the power and the versatility of sound-card-based measurements. To illustrate the usefulness of measurements in the design process, Yaniger also explores the effects of load on power supply noise for a common IC regulator circuit. This article was originally published in audioXpress, November 2015.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements

Part 1 of an article series that looks at some of the available options and methods to create a low-cost system (emphasis on “low-cost”) for lab-grade audio electronics measurements. Focusing on solutions within easy reach of budget-conscience hobbyists, the goal is to demonstrate how you can generate useful data, similar to the graphs and charts in the audio review magazines, but without the expense. A great test and measurement article series by Stuart Yaniger, which started to be originally published in audioXpress, June 2015.
